Limits: Oil Pressure and Temperature

Question 1

Oil Press at Low RPM in RGB

Answer 1

250 except start and warmup 50

Question 2

Oil Press at Normal RPM in RGB

Answer 2

250 except start and warm up 150 PSI

Operation below 150 psi when rpm is below 100% is permitted. If RGB

Question 3

Oil Press at Low RPM and Normal RPM in PWR Section

Answer 3

100 start and warmup only, then 50-60 PSI

Question 4

Oil Press Low Light on in PWR Section

Answer 4

40 PSI

Question 5

Oil Press Low Light on in RGB Section

Answer 5

130 PSI

Question 6

Allowable Oil Press Fluctuation in RGB

Answer 6

+/- 20 PSI

Question 7

Allowable Oil Press Fluctuation in PWR Section

Answer 7

+/- 5 PSI

Question 8

Normal Oil Temp

Answer 8

60-90 C

100 C oil temp is maximum allowed only for 30 mins in Beta and 5 mins in Alpha

Question 9

Oil Hot Light On

Answer 9

100 C

Question 10

Max Time for Oil Hot Light On (Beta)

Answer 10

30 min

Question 11

Max Time for Oil Hot Light on (Alpha)

Answer 11

5 min

Question 12

Min Oil Temperature for Start

Answer 12

-40 C

Question 13

Oil Pressure for Start

Answer 13

Positive Pressure by 35% RPM

Question 14

Oil Temperature for Takeoff

Answer 14

90 C (100 C limits in Alpha and Beta apply)
60 to 90 C is normal
40 C (Operation with temp from 50-60 C is permitted under extremely cold conditions provided all oil pressure limitations are maintained, when temp reaches 40 C Max power may be applied)

Question 15

After returning to a positive G condition, following a negative G flight, shut down the engine if oil pressure fluctuates for more than ___ seconds

Answer 15

15
